Patent EP-0321764-A1 (EP)
Inventor: ANDERSEN HANS
IPC: A61N1/37
Filed: 1988-12-05
Abstract: An event detector, useful, for example, in pacemaker technology, detects signal portions which have characteristic events ex­ceeding a certain established threshold. An optimal setting of the detector sensitivity is achieved by passing the input signal through a circuit which measures the signal's maximal values, then establishes the difference between the maximal values and the established threshold, and, in a preferred em­bodiment, controls the threshold in accordance with the difference and a given desired threshold value. The desired threshold value can be based on, for example, difference histo­grams or trend data. The event detector can be designed to respond to a variety of signal parameters, such as amplitude and/or slope.

Abstract: A pulsed droplet ink jet printer has at least one channel (24) communicating with a nozzle (40). The side wall (30) of the channel is formed as a shear mode piezo-electric actuator. Electrodes (38, 39) applied to the actuator enable an electric field to be applied such that the actuator moves in the direction of the field to change the liquid pressure in the channel and thereby eject a droplet through the nozzle (40). The actuator can be made in two parts (32, 33) so as to deform, in cross section, to a chevron formation.

Abstract: A membrane keyboard has two spaced flexible membranes (1 and 2) carrying contact pad assemblies. Acoustic pads (15) of expanding ink are printed on the top surface of the upper membrane (2) between the contact pads (4) and the key buttons used to operate the contact switches formed by the pairs of opposed contact pads, thus reducing the acoustic noise and improving the contact bounce characteristic. 
     Optionally, printed expanding ink is also used to form the spacer (5) between the membranes (1 and 2).

Abstract: An article of glassware, particularly a glass container, of increased strength is made by a process in which the parison is treated in a manner which will cause the glass in the outer surface layer of the formed glassware article to be in a state of compression. Preferably a glaze having a coefficient of thermal expansion lower than the coefficient of thermal expansion of the glass of the parison is applied to the outer surface of the parison. Advantageously, the glaze is applied to the parison by a flame spray method or by dipping the parison into a fluidised bed containing powdered glaze. 
     As an alternative, the glaze applied to the outer surface of the parison may be capable of being at least partially crystallised, after the glassware article has been formed from the parison, to produce an outer surface of the glassware article having a lower coefficient of thermal expansion than the base glass of the glassware article. 
     Alternatively to the application of a glaze, glass in the outer surface of the parison may be chemically changed so that the surface glass in the parison has a higher transformation temperature than the remainder of the glass in the parison.   
     Additionally, the interior surface of the parison may be treated by a material producing active gases so that a compressive layer is produced on the internal surface of the final glassware article, at least partially balancing the compressive layer in the outer surface of the glassware article.

Abstract: In a semiconductor integrated circuit a light-detection circuit (1- 2) is constructed whose output signal (S) can be exploited in order to combat manipulations by fraudulent persons engaging in an operation to remove the cover, or to extract the card when the integrated circuit is inserted in a card of the banking type, or even in depassivating the top layer for protecting this integrated circuit, with the intention of disclosing the secret operation of the circuit or of modifying its characteristics. The detector comprises a current generator (2) delivering a limited current of intensity (Im) which flows into a reverse-biased electronic junction (1). When the junction is subjected to the light, the reverse current permissible in the junction increases. As the current generator is not able to deliver a higher current, the voltage across the terminals of the junction drops. This voltage drop is exploited as an indicator of the illumination.

Abstract: A ceramic-reinforced aluminum matrix composite is formed by contacting a molten aluminum-magnesium alloy with a permeable mass of ceramic material in the presence of a gas comprising from about 10 to 100% nitrogen, by volume, balance non-oxidizing gas, e.g., hydrogen or argon. Under these conditions, the molten alloy spontaneously infiltrates the ceramic mass under normal atmospheric pressures. A solid body of the alloy can be placed adjacent a permeable bedding of ceramic material, and brought to the molten state, preferably to at least about 700°C, in order to form the aluminum matrix composite by infiltration. In addition to magnesium, auxiliary alloying elements may be employed with aluminum. The resulting composite products may contain a discontinuous aluminum nitride phase in the aluminum matrix and/or an aluminum nitride external surface layer.

Abstract: The beam is subdivided longitudinally into sections in function of the anticipated static load or, when the whole beam is to be subjected to a single characteristic load, it is considered to constitute a single section; the web of the section(s) is then cut into two halves along a cutting line (3) composed of straight lines and curves of variable periodicity in a rotationally symmetrically manner in relation to the point (o) located on a median line (k) perpendicular to the length of the sections. The dimensions of the castellations so obtained are thus adapted to the load. One of the halves (2) so obtained is rotated through 180 DEG  about the median line, the two halves of the beam are jointed together to form a web, and, in the case of several sections, the castellated sections so obtained are joined together.
